Processing "vignette" files
Is there any way to process the "vignette" documantation files?
I have been looking at the bioconductor packages and most of them have
*.Rnw files in doc directories. They look like regular TeX but have
sections showing R code that seem to choke TeX.
Thanks,
Andy

readline with R-1.4.0
Hi,
I am not sure if this is a bug, so I am posting it here. I also searched
the FAQ file for the readline string and did not find anything about the
behavior below.
I just successfully rsync'ed, compiled and tested R-1.4.0 on my RH 7.2
Linux machine. I encountered one problem though. When running ./configure
I noticed that I was getting errors from the readline library. Although

strange slowness of plot
I just ran into this strange behavior.
y <- rnorm(1000)
x <- seq(0, length=length(y))
plot(x, y, type='l', lty=1) - instantaneous
plot(x, y, type='l', lty=2) - 18s plotting lines + 15s plotting axes
= 33s
plot(x, y, type='l', lty=3) - 76s ,, + 75s

new lattice/grid
I just installed R-1.4.0 on my Win2k machine from SetupR.exe. Everything
seems to be fine with the base and recommended packages. However, when I
install the lattice and grid packages they do not seem to work. Everything
I try results in something like this:
Instruction 0x00543f06 refernced memory 0x00000000. The memory cannot
be "read".
and I am getting kicked out of R.

PNG diver problem
Hi,
I am having the following problem and I am not sure if this is bug or I am
missing something obvious.
I have a bunch of R functions that automatically process large data sets.
The processing produces several numerical summaries and several graphs
which are subsequently put in reports. I usually do my processing in R
BATCH mode on a Win2000 machine.
All the graphical functions in my package

Compiling 1.3.1 under RH Linux
Hi,
I am trying to compile R-1.3.1 under RH-7.2 Linux. I used the old gcc
compiler (kgcc) and the compilation went fine. I can start R and run some
rudimentary tasks with no problem. However, when I did
make check
I got the following error in base-Ex.Rout

mixture of 2 normals - starting values
Hi,
I have a problem of estimating a mixture of two normal distributions. I
need to find the starting points automatically, since this is a part of a
larger piece of image processing code.
I found the mix2normal1 function in VGAM package that mentions a method of
finding starting values for mu1 and mu2 but refers the reader to a book by
Everitt and Hand. Unfortunately, I do not have an easy

odesolve check fails
Hi,
I just installed the odesolve package and ran the check command on it. It
failed trying to execute
library(gnlm).
Sure enough, there is no gnlm library on my system and I could not find it
on the CRAN archive either. Am I missing anything obvious or is gnlm some
private library that somehow found its way into the example section of
odesolve?
Thanks in advance,

Re: Problems with rgl package
I also downloaded the rgl package (after reading recent Uwe Ligges' post)
and installed in on my Win2k Pro sp2 machine. It seems to work with no
problems. I ran most of the examples, including the hist3d one, and all of
them worked fine.
A couple of thoughts. I have administrative priviliges on my machine.
Could this possible make a difference. The rgl library uses OpenGL. Is it

1.4.1 R CMD check broken?
I am not sure if this is already known. I checked BUGS and found some
references to similar behavior when R_HOME is set?
Here is what I get:
(1) Fresh build of 1.4.1 under Linux/RH-7.2. All tests pass.

Small request.
This is (hopefully) a small request.
I routinely build (and test) both R versions from sources on my system
(WinXP). I would like to be sure that I have the current version of
Rtools. I always go to Robert Murdoch's site "Building R for Windows" and
check the latest news. Everything I need is explained there, except I
never know if I have the most recent version of Rtools.exe.

bug in as.POSIXct ?
I think that there is a bug in the as.POSIXct function on Windows.
Here is what I get on Win2000, Pentium III machine in R 1.8.1.

small bug in plot.rpart?
Hi,
This happens in 2.8 and 2.9. I am posting this here because I am not sure
if one should use bug.report for reporting bugs in unreleased versions.
I was trying to run the example from the help page of plot.rpart. I got

Probit Analysis
Hello all,
I have a very simple set of data and I would like to analyze them with
probit analysis.
The data are:
X Event Trial
100 8 8
75 8 8
50 6 8
25 4 8
10 2 8
0 0 8
I want to estimate the value of X that will give a 95% hit rate
(Event/Trial) and the corresponding
95% CI. Anyone can offer some help? Thanks!!

Xeon CPU and ATLAS
I am about to get a new machine at work - an IBM Intellistation with the
Xeon 2.8 GB processor. It will run Windows 2000. I would like to install
the proper ATLAS dll for this machine, but I am not sure if Xeon is P4?
Does anybody have any experience with Xeon?
Thanks in advance,
Andy

R-2.7.0 RC (2008-04-20 r45403) fails fullcheck
A strange thing happened. After installing the most recent RC version of

installing it I ran "make fullcheck". I got as far as testing recommended
packages and I got the following:

Data frame question
Hi,
I have the following question about creating data frames. I want to
create a data frame with 2 components: a vector and a matrix.
Let me use a simple example:
y <- rnorm(10)
x <- matrix(rnorm(150), nrow=10)
Now if I do
dd <- data.frame(x=x, y=y)
I get a data frame with 16 colums, but if, according to the documentation,
I do
dd <- data.frame(x=I(x), y=y)
then str(dd)

small error in regression tests
I just r-sync'ed the r-devel version of R-1.7.0 (2003-03-11), compiled it
under RH-8.0 and ran make check. The reg-tests-2 fails at the very end
with the message stating that "object cement was not found". It looks like
this piece of the regression test is new to version 1.7. The the piece of
code generating the error is:

Anybody ever notice...
It could be a little bug or a fault in my setup but I notice that after I
end an Rcmdr session I can't restart it without restarting Rgui (Windows)
Do I need to add something to my environment variables? Is it an issue with
Tcl/Tk or it's settings? Or what?
It is not a big deal but if someone has a fix for this I would give it a
shot I usually start Rcmd from the console library(Rcmdr)
